His brother has taken a job at their father's old company - and married Efe's childhood sweetheart. When their witness returns, the original murderers set about taking care of him once and for all. But when they get the wrong twin, Efe who has been brought up as a humble fisherman, has no option but to adopt his brother's high-flying identity and lifestyle to infiltrate the inner circle that has destroyed his once powerful family.
